Since I've heard some infomation of this 1990s rare movie "Cartoon All-Stars to the Rescue" I have been thinking about doing a collab with of this idea.

Many great cartoons stars (Mostly from Nickelodeon and Cartoon Network) gather around to find that some evil cartoon villains are having plans to take over the world. The heroes must work together to stop evil once and for all.

So far, the cast for this series would be one or a few of the cast from:
Hi Hi Puffy Ami Yumi (Cartoon Network)
My Life as a Teenage Robot (Nickelodeon)
Foster's Home for Imaginary Friends (Cartoon Network)
Danny Phantom (Nickelodeon)
The Powerpuff Girls (Cartoon Network)
The Fairly Odd Parents (Nickelodeon)

And guess what? I found three clips of the original Cartoon All-Stars special[link][link]
And this one I consider it a music video[link]

Maybe someone (ie Dogbert, Thanos, a child named Mindy) was playing around with God's computer and caused a glitch in his 'Universe simulation'...

Perhaps Doctor Bong (one of Howard the Duck's annoying adversaries) built another television-altering invention...and it short-circuited, causing the characters of every (animated) television show to appear in the 'real world'...

Or perhaps Jhonen Vasquez, Steve Purcell and John Kricfalusi, creators of some of the strangest 'infinite universes' ever published/broadcast, were captured by Mojo Jojo as part of yet another fiendish plot to take over the world, completely unaware of the destructive power he was about to unleash...

Or maybe someone just want to create a readable crossover story... *points to the storyline in the original post*

Whatever the reason, it'll be interesting to see which characters will be included and how they'll react to each others' appearance/mannerisms in the story. (although I will admit that some of the crossovers I've read were better than most of the intercompany examples that were broadcast. Kim Possible/Stitch, anyone?)

Let's just see what happens. I've enjoyed the comics that Bleedman has posted so far so, if he hasn't burned himself out on his own projects, it could be worth the wait.

(Then again, I wonder how Fiona would handle a change in drawing style as she met certain licensed characters or those of your other pen-and-ink projects)
